. As seen in the drawings, the hereindisclosed press has a stationarypress-head cylinderlo. The cylinder lfz is permanently. attached bybrackets 16 to-fa stationary cross head 17. The cylinder 15 ofthepresent disclosure is int'eriorly equipped in sulos tan;

' tially" the same manner and ,with similar elements as thoseshown in" apatent granted, to meunder date ofJuly 18, 1916, and umbered'1,19l,709,to whichapatent crossref+ erenceis here made. fllVherea's, however,thepress-head cylinder in the former patentis reciprocated togetherwiththe cross head which it is supported, 'inthe present ma- 7o chineboth the cylinderl'5 and the cross'head 1 7 are stationary. I lhecrosshead 17 is supportedjhy framinglegs 18,1 the feet '19- whereof form thesupportinglfoundation for the machine. Theleg's 18 at the lower endsYjSwhich prevents the said] legs v eral extremities-of the heating table23, and

the reinforcing finst2 lthereo-f. The table 23 v v has a centrallydisposed,{cylindrical chamher for holding a crown shape above a tip petjmember, movably 'mounted therein and iSj adapted for'supporting aremovable brini' die 25, the, contour whereof c0rres1'5onds -to" theshape to be imparted to the brim of the p'res'sureis 'applied by aflexible hat when face forming theinterio-r ofthecylinder15,"9o l asmore fully set forth in-thejpatent' abovef referred to. r r 1 Theweight; of the ,table 23 and parts attached thereto ispa'rtiallycounterbalanced. by'the block 26. I he block 226 is operativelyconnected with the runner'blocks 22 ."byca- 1 bles 27, which arerove'd'over; pulleyseg-- ments 28 and 29', and are connected to the vblocks 22 bypivot heads 30' andrpins 81.

The opposite ends of'fthecables 27 are at 10o tachedto the eyelets32in'eye-bars 33.; The eye-bars 33 are'provi ded as guides for supg1,429,0ee

plemental weight 34, which may be added to the block 26 to augment theeffective weight thereof.

The table 23 and parts supported thereby are elevated and lepressed by amechanism manually controlled through a lev r bar 35, the hand grip 86whereof is grasped by the attendant of the machine when desired, to movethe lever from the position saown in Figure 3 to that disclosed inFigure 2, the result of which is to move the table 23 into closedrelation with the cylinder 15.

I The mechanism for elev ting the table 23 above referred to, con tsprimarily of toggle frames the links 3'? whereof are imauy connected bypins 39. The pins 39 also serve to connect the strap links 10 with thelinks 37 and 38. The strap links 46 are connected by pivot pins n, withroclnng arms 4:2 which are mounted on the square shaft The square shaft4-3 is pivotally mounted in hearings in brackets 44 eiztended from thebolting plates 45. The brackets i l are. integral with the plates 45.and have feet a6 'which rest against the web of one of the l-beamsframing the adjustable cross, head 917 On the lateral extremities of thecross-head 4'? is integrally formed a runner block ii-7 slidablyconfined in each guideway to hold the crosshead in vertical alignmentwith the machine. The cross head l? is complementary to the cross head17, and is structurally connected with and suspended from said crosshead 17 by the four suspension rods 4 8. The rods 4-8 are held 1nparallel ahnement by the bolting plates l-5 and 49, and extend throughrecesses in the exposed flanges of the I-beams forming the cross head.The extremities of the rods 48' are'threaded and provided with nuts 50.The nu ts are adjusted to extend or contract the distance between thecross heads 17 and 47. This distance, it will be understood, correspondswith the height of the die 25 and the consequent working level of thetable 23 in relation to the cylinder 15.

As seen best in Figure 6 of the drawings the link 3'? has arearwardly-extended toe 51, a rearwardly-extended heel 52 being formedon the edge of the links 38. The abutting surfaces of the toe and heelmentioned are dressed or machined to rest firm- 1y upon each other whenthe toggle frames formed by the lin Is 37 and 38 are in locked positionor in the position where the planes of the two frames are angularlydisposedi the connecting pivots thereof having passed the alanecoincident with the hinoge nivots' thereof. In this position, the toes5] and heels prevent the frames from further forward movement whenpressure is applied "to the table while the angular disposition of thetwo frames prevents a rear ward movement of the joint of the saidframes. It is obvious that the predominance in length of the lever 35over the arms 42, facilities the forceful closure of the toggle frameswhereby any miscalculation in the adjustment of the cross-heads l7 and47 may be accommodated without requiring readjustment thereof.

It will be understood that the table 23 and the die 25 carried therebyare lifted by the toggle frames and seated against the flexible innerwall of the cylinder 15 forcefully.

In the manufacture of hats for which the present machine is particularlydesigned the rough shapes steamed. Before elevating the table ;,3 anddie :15 thereon, one of the rough shapes at each operation, is adjustedto I said die. l l hen the die is closed, the upper surface thereofpresses upon and forces the brim of the hat against the inner lining ofthe cylinder The crown 53 with which machines of this character areusually provided is encompassed by a crown :inold 54c, section'whereofis shown in Figure 8 of the drawings, which rests on the tip plate 55.The tip plate 55 and the table 23 are steam-heated. The tip plate has asteam space 56 provided therein, which is connected by means of the pipe5?, with a steam space 58 in the table 28. As best shown in Figure 8,the pipe 57 is telescopically mounted in a tube 59, which is connectedby a short pipe nipple 66 with said steam space 58.

its shown in Figure 2 of the drawings, steam is delivered to the space58 in the table 23 by a supply pipe 61. After circulating through thespace 58, nipple 60, tube 59, pipe 57., and steam space 56, the steampasses from said steam space 56 by way of the pipe 62 and tube 63 to awaste pipe 64. A telescopic. connection is provided between the tube 63and the pipe A supply of steam is provided for the table and the crowntip in this manner, the heat whereof is transmitted to the die 25 andmold 542. 7

As shown best in Figure 8 of the drawings, the telesco aic connectionbetween the pipe 5'? and the tube 59, and the pipe 62 and the tube 63,is required by the nece sity for raising and lowerin the mold. 5a, toadjust the press for the manufacture of hats having crowns of varioussizes and shapes. To do this, the tip 55 is raised and lowered.

Tn the present machine, to raise and lower the tip 55, screw threadednut 65 is provided. The nut 65 thread engaged with an elevating screw66, as shown best in igure 8 of the drawings. The upper end of the screw66 is connected with a tubular extension 6'? of the tip 55, by means ofa pin 68. The nut 65 has an annular flange 69, supported. by a coverplate 70 at the bottom of the tubular extension 71 of the table 23. Thecover plate 7O is centrally provided with'a circular opening, throughwhich a raised crown -headof the nut 65 extends. The head haspermanently mounted thereon a "ratchet 72, the teeth whereof are engagedbythe tooth end of a springseated pawl 73. To seat the pawl 73, a spiralspring 7 1 is provided as shown in said Figure 8. The tooth 7 5 of thepawl 7 3 is beveled at one side to engage the teeth of the ratchet onthe flat side thereof, a form of pawl-'and-ratchet well known to theart.

Provision is made by the use of the ratchet and pawl for reversing theoperation of the pawl on the ratchet, which is accomplished byretracting the pawl 7 3 and rotating it onthe axis to presentthe squaredface thereof in relatively opposite rotary directions of the ratchet 72.The pawl 73 is mounted in the hub of a lever 76, the hand grip 77 ofwhich, as shown best-in Figure 3, is within easy reach of the attendantof'the machine. By operating the lever 76, the attendant can readilyincrease or decrease the proportionate amount of pressure of the machineon the crown without-affecting the pressure which is exerted uponthebrim of the hatbeing pressed.

1 The pressure relied upon for pressing hats is hydraulic, water underpressure being admitted to the crown bag 53, by way of the pipe 78, tube79, pipe'80, and tube 81, which hasa-screw threaded extension 82. Thetube opens within the crown bag 53 and a rigid -top plate thereof todeliver water to the said bag for pressing the crown independently ofthe .rlm. A screw nut having a hand wheel 83 is operated in the bowedbridge 84 to raise and lower the tube 81 and thecrown bag supportedthereby. To show the pressure on the water employed 'in the hydraulicoperation, a pressure gage 85 is employed. V

WVater under pressure-is supplied by the pipe 86, shown best in Figure 1of the drawings, an extension 87v thereof entering the cylinderla withinthe space covered by the flexible lining of the said cylinder, whichlining corresponds with the upper shape of the die 25. A valve 88controls the flow of water through the pipe 86. I

In the operation. of the machine, the attendant having adjusted theoperating position of the cross head &7 to the working position of thetable 23 and partssupported thereby, places on the die 25 a rough shapeand first gripping the hand rest 23, he grasps the hand grip 36 of thelever 35,

and moves the same from the position shown in Figure 3, to that shown inFigure 2, with the result that the toggle frames having the links 37 and38 are straightened and thrown past the center of a plane coincidentwith the pivots of: the said frames until the toes 51 of the links iengage and rest upon the heels 52 of the said links. In this position, therough hat. shape is given a relatively slight preliminary pressure bythe inner lining of the cylinder 15, and by the outer surface of the bag53. In this position, the valve 89 having been turned off, the valve 88is opened and water from the pipe 86 is permitted to flow through thepipes 78 and 87, respectively,-

to the bag 53, and the cylinder 15, imparttain pressure on the crown ofthe hat after the pressure is relieved from the brim thereof, the valve91 isclosed before the valve 89is opened. When, therefore, the'v'alve89.;is opened, it is obvious that pressure will be relieved from thecylinder 15 without relieving pressure from the bag 53.

The pressure surface of the bag 53 and of the brirndie 25 being great,the resultant strain on the machineryis correspondinglygreat. Machinesof this character have been; subject to breakage for 'this reason. It isto'overcome this objection that the links 37 and '38 and the brackets 16havebeen disposed in line and intermediate the-centerof' the machine andthe rods 48 connecting the cross heads 17 and 17 By thisarrangem'ent,the lines of resistance to the strain are balanced to equalize thestrain and to avoid tortional stresses on the mechanism:

It is obvious that the rapidity with "which the machine may be'operatedis augmented, when by the operation ofthe single lever 35, the clampingelements of the machine'a're closed and locked in operative position. I
